A man was walking down the street when he was accosted by a particularly dirty and shabby-looking homeless man who asked him for a couple of dollars for dinner. The man took out his wallet, extracted ten dollars and asked, "If I give you this money, will you buy some beer with it instead?"

"No, I had to stop drinking years ago," the homeless man replied.

"Will you use it to gamble instead of buying food?" the man asked.

"No, I don't gamble," the homeless man said. "I need everything I can get just to stay alive."

"Will you spend the money on greens fees at a golf course instead of food?" the man asked.
